HDR: The Good, the Bad and the Beautiful
This is a pdf of the slides used at Kevin's BSC Expo presentation to introduce HDR. Learn more about the changes that come with HDR on the 2 day CA301: HDR Colorist Masterclass
Finalcolor Test Patterns
The following are some of the test patters I use in classes. You can download the uncompressed HD tiff files for free. The original files are UHD uncompressed and are available by file transfer for £20 (with 3 bonus tests otherwise only available in my new classes). The page images are low res jpg, so you will need to use the download links below.
This file has a digital Macbeth surrounded by black and white Pluge patterns and a simple identifier to show full range or video signals. It also has patches showing full range, video and log black and white points. Perfect for checking monitor brightness and contrast without a probe.
This file contains an image in four versions, ACES, BT.709, DCI P3 and HDR PQ BT2020. The original images are available from Acescentral.com where you can get the ACES image as an .exr. This is not an ACES image but this frame is an easy way to tell what colourspace you are monitoring. Display the frame and look to see which of the 4 patches looks correct on your monitor. Then take into account everything in the path from the player to the screen, e.g. graphics or video cards and LUT boxes. These are the most common master formats.
This frame has an APL of .45 and is designed to evaluate HDR potential in a display. The display should be set to 2020 and 2084 for correct use. The left patches show shadow performance (LCD and OLED) the right patches set the brighter displays apart. The center strips show primary performance, bit depth and tone mapping.
This file has a 21 step gray step, followed by full range and video 11 step wedges. It also has red, green, blue and grey gradients from black to white and 16 x 9 framing arrows. Great for checking gamma, color tracking and bit depth on monitors and LUTs. It also shows full Video and data levels.
This image contains the infamous Marcie, Kodak LAD frame in its original Cineon log with an ACES copy (originals from Kodak and Academy ACES). Together with a 21 step grayscale this is a good reference image to check monitoring setups. The Cineon Log Marcie can be used to evaluate LUTs. Please note that the ACES Marcie is limited by the Tiff format and will appear correct but clipped to film print values in an ACES workflow . Use the original Academy ACES .exr file for testing full range ACES pipelines.
This is a desktop that I have been using for many years. It is great for checking display calibration and essential if you often do presentations on unknown devices. The grayscale shows if the display is correctly presenting the full range of tones and if there are tracking issues some of the steps will show marked color changes. The center logo tests saturation.
